Protein

Glutathione S-transferase class-mu 26 kDa isozyme

Gene
N/A
Organism
Schistosoma japonicum (Blood fluke)
Status
Reviewed - Annotation score: 4 out of 5- Experimental evidence at protein leveli

Functioni

Conjugation of reduced glutathione to a wide number of exogenous and endogenous hydrophobic electrophiles.
GST isoenzymes appear to play a central role in the parasite detoxification system. Other functions are also suspected including a role in increasing the solubility of haematin in the parasite gut.

Catalytic activityi

RX + glutathione = HX + R-S-glutathione.
